Lone Travelling advice

I'm planning on travelling in a year or two, unsure on destinations yet but the vision i have is to travel off the beaten path, explore, live off the wild if i had too. I hope to spend a year away at a time, first off i would start on a smaller adventure for a few weeks rather than jump straight into this.

Always have wanted to live a travellers lifestyle, just wanted some advice really, if any of you have spent a long time travelling alone backpacking & living of the wild i would really appreciate a talk,
